Claims. .(Ci. Z4874) This invention relates to new and useful improvements in pipe hangers for use particularly although not necessarily, on ships and has for its primary object to provide, in a manner as hereinafterset forth, a pipe hanger which is adapted to be eirpeditiously installed beneath an insulated deck with aminimum or damage to the insulation.

Anoher very important'object of the present invention is to provide, in a hanger of the aforementioned character comprising a saddle for receiving the pipe, novel means for quickly, firmly but removably securing the pipe in said saddle.

Still another important object of the invention is to provide an improved pipe hanger of the character set forth which is readily vertically adjustable relative to the deck or other overhead supporting structure.

Another object of the invention is to provide an im- 7 proved hanger of the character described which is adapted to accommodate various sizes of pipe within a given range. V

Other objects of the invention are to provide an improved pipe hanger which is comparatively simple in construction, strong, durable, compact, of light weight and which may be manufactured and installed at low cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which: 7 FIGURE 1 is a perspective view of a pipe hanger constructed in accordance withthe present invention, showingthe device installed; i

FIGURE 2 is a" view vertical section through the rear portion of the device, showing same installed;

FIGURE 3 is a sectional view on an enlarged scale through the connected end portions of the pipe securing strap or band, taken substantially on the line 33 of FIGURE 1;

FIGURE 4 is a vertical sectional View on an enlarged scale, taken substantially on the line 4-4 of FIGURE 2;

FIGURE 5 is a perspective View of the hanger per se without the suspension stud or rod;

FIGURE 6 is a view in side elevation of another embodiment of the hanger, showing same installed;

FIGURE 7 is a bottom plan view of the embodiment of FIGURE 6;

FIGURE 8 is a view in transverse section, taken substantially on the line 8 -8 of FIGURE 6; and

FIGURE 9 is a perspective viewof the clamp which is used on both embodiments of the hanger.

Referring now to the drawing in'detail, it will be seen that the embodiment of the present invention which has *been illustratedin FIGURESI to-S, inclusive, of said drawing comprises a threaded suspension rod, shank orstud 9 of suitable inetal. Thesuspension stud 9 may also be of any desired length and diameter. The stud 9 extendsflupwardly through an opening 1% provided there for in the insulation 11 beneath the steel ship deck 12 and has its upper end portion riveted or otherwise anchor ed in said deck, as indicated at 13. In the installation shown, the steel deck 12 is apertured as indicated at 14 to accommodate the stud 9.

' Removably and adjustably mounted on the lower end portion of the suspension stud 9 is a generally U-shaped The generally ICC which terminates in a right angular 1y bent, horizjon'tel free end portion or flange '17 which is aperturie d; to acf co'mmodate the stud 9. Threadedly mounted on. the" 9 is a plate-likenut 18 beneath which the flange 17 of the saddle 15 is e'ngaged. A nut 19 is threaded on the stud 9 beneath the flange 1 7. ,rhe nuts 215E119 ad justably secure the flange 17 on the stud 9 in an obvious manner. 7 i A,

The saddle 15 is for the reception of the pipe to hung, as indicated at 20. A longitudinally split, tubular pad or sleeve 21 is provided on the portion of the pipe 20 which rests in thesaddle 15. clamp 22 secures the The clamp 22 comprises a flat metallic band; or v H p 23 which is threaded through a trarisverse slot 24 pi-of vided therefor in the upper portion ofthe back leg 16 of the saddle 15. One portion of the strap 23 passes beneath the saddle 15 and the other end pbrtionofsaid' strap passes over the pipe 20. The end portions; of the v strap 23 are adjustablyand detach'ably connected through the medium of a metallic connector or clip 2h. The clip or connector 25 includes; in the embodiment shown, a rectangular metallic plate 26 having formed integrally with one end portion thereof a transverse. loop Formed integrally with the other end portion of the plate 26, on the longitudinal sides thereof,1 are bendable cars 28'. One end portion of the strap 25 inserted through the loop 27 and is downwardlyand reversely beht in a manner to provide a hook or, the like 29 ifr wllich plate 25 is engaged. The other end portion of; the strap 23 is inserted between the outstanding ears 28 over the other end portion of said strap, inserted through the loop 27 and outwardly and reversely bent in a mahr ertc} pr givide a hook 30 in whichthe loop 27,, is engaged and which extends between the'ears 281 The ears 28 are ther l clinched on the reversely bent end portion' or hook 30 and the connection iscorhplete, )1 4 a u i It is thought that the use of t he hanger will readily apparent from a consideration of foregoing Of course, to install the device the threaded suspension rod; shank or stud 9 is mounted on the deck structure or other overhead support beneath which the pipe is to be mounted. The saddle 15 is then slipped on the stud 9, adjusted to the desired position and secured between the threaded

elements

18 and 19. It will be noted that the construction is such as to permit rotary as well as vertical adjustment. With the protective pad or sleeve 21 thereon, the pipe 20 is then engaged in the saddle 51 and firmly secured through the medium of the clamp 22. It also will be noted that the construction is such as to accommodate various-sizes of pipe. An opening 31 in the flange v studs 32 which are suspended from the insulated deck structure or other overhead support 12. Adjustably and removably mounted between'the lower end portions of the studsSZ is a'substantially inverted U-shaped saddle 33 of suitable metal. The saddle 33'is provided on its ends with integral, outwardly projecting horizontal ears or flanges 34 through which the lower end portions of the studs 32 pass. The portions 34 of the" saddle 33 are secured in adjusted position on thestudsSZ between pairs of nuts 35 threaded on said studs. V v

The saddle 33 is for the reception of the pipe to be hung, as indicated at 36. The portion of the pipe 36 which isengaged in the saddle 33 is provided with a pro- 2 U gated openings or slots 38. The openings or slots 38 are for the passage of the straps 23 of a pair of the clamps 22 which secure the pipe 36 in the saddle 33. This is shown to advantage in FIGURE 7 of the drawing. It will be observed that the straps are threaded in opposite directions through the openings 38 while the clips or connectors 25 are located beneath opposite side portions of the pipe.

In use, the studs 32 are suspended from the deck structure 12 and the saddle 33 is mounted between said studs.

The pipe 36 is then engaged beneath the saddle 33 and the clamps 22 are applied. The saddle 33 is adjustable vertically on the studs 32 by reason of the nuts 35. This vertical adjustment may be made either before or after the pipe is secured in the saddle. This also applies to the embodiment of FIGURE 1 of the drawing.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
